Automobili Lamborghini presents the Lamborghini Sian Roadster: a limited edition, open-top hybrid super sports car engineered around Lamborghini’s iconic V12 engine.
“Sián’ in local Bolognese dialect, meaning ‘flash’ or ‘lightening’, indicates the unique hybrid technologies and unsurpassed Lamborghini and hybrid performance, and the new car is produced in a limited series of 19 units, all already sold!
The roofless design of the Sian Roadster puts an exclusive group of drivers in one of the most spectacular cockpits ever: always open to the sky; resonating with the inimitable V12 sound from the most powerful Lamborghini engine to date.
“The Sián Roadster encapsulates the spirit of Lamborghini,” says Stefano Domenicali, Automobili Lamborghini Chairman and Chief Executive Officer. “It is the expression of breathtaking design and extraordinary performance, but most importantly embodies important future technologies. The Sián’s innovative hybrid powertrain heralds the direction for Lamborghini super sports cars, and the open-top Sián Roadster affirms a desire for the ultimate lifestyle Lamborghini as we move towards a tomorrow demanding electrification.”
The Lamborghini Sian Roadster asserts the futuristic design of the coupé, but as a true roadster adds a new purity with the open-air cabin. The Sián’s long sculptured contours and characteristic aero wings give the Sián Roadster an unmistakably powerful profile. The car’s very low front, with integrated carbon fiber splitter, houses the iconic Lamborghini Y-shape headlights.
The extreme and strong rear of the car incorporates Lamborghini’s evocative hexagon design, including six hexagonal taillights inspired by the Countach. The rear wing is integrated within the profile and extends out only during the driving to enhance the performance.
Electrification and hybrid technologies:
The Sian Roadster’s hybrid system provides the highest power possible via the lightest solution, combining the V12 engine with a new powertrain. A 48-volt e-motor, delivering 34 hp, is incorporated into the gearbox to provide immediate response and improved performance. The e-motor also supports low-speed maneuvers such as reversing and parking with electric power.
. Three times more powerful than a battery of the same weight and three times lighter than a battery producing the same power, the electric system with the supercapacitor and e-motor weighs only 34 kg, thus it delivers a remarkable weight-to-power ratio of 1.0 kg/hp.
This advanced technology combines with the V12 engine, which incorporates titanium intake valves and is uprated to 785 hp (577 kW) at 8,500 rpm. Combined with the additional 34 hp from the hybrid system, the Sián Roadster delivers a total of 819 hp (602 kW) and reaches a top speed of over 350 km/h.
The Sian Roadster accelerates from 0 to 100 km/h in less than 2.9 seconds. The improvement in elasticity maneuvers is even more evident.
